Linear Estimates for x and y

When two-variable statistical information is stored in the statistical registers, an estimated y value can be calculated using a new x value or an estimated x value can be calculated using a new y value.

To estimate y:

¾Enter the new x value

¾Touch r y, r

To estimate x:
